The SEDIS belt was ahead of it's time, and also very hard to find for a long time. "Wet" timing belts are now much more common.

The valve cover is made out of magnesium, not anyone can powdercoat it. You also need to paint or clearcoat the "16V", sanding it won't do as raw magnesium won't stay shiny for long. On top of that the plug cover is made out of plastic so it may be hard to have the same aspect on both parts. Also before doing any work on the valve cover look for stripped treads, you may need some M6 helicoils if lucky and if not a M8 tap.

It's not 75W80 for the gearbox?

Now thant PSA is part of Stellantis the return plan for Peugeot is cancelled, obviously the new group has now more than enough market share in the US. The silver lining is that once the US cars start using the same platforms it would be much easier to relaunch Peugeot. There is still room for one acces premium brand between Fiat and Alfa Romeo, it should be either Peugeot or Opel/Vauxhall.

The block looks great in satin black.

Then it's even worse than France, for us any swap or mod that was done legally in the past is still ok today. The car must respect emissions laws from the time it was made and nothing more.

It seems that your country is starting to look like mine. If you can still get away with some mods or even a swap it's now or never.

If the rods are located by the pistons like in the XU9J4 then you're fine but it's quite uncommon.

A repair kit is cheaper than that: https://cis-jetronic.com/index.php?rt=product/manufacturer&manufacturer_id=33

7/16" isn't the head, it's the tread. On my 309 the heads are neither metric nor the standard imperial size and some are low profile, add thread lock on top of that and you can have lots of fun changing a seat belt.

Brake boosters, brake rotors and clutches diameters are often imperial sizes. You can also find 7/16"-20 (UNF) seat belt bolts for some reason.

0242.50 for the sensor, the gauges are 6135.75 for Veglia clusters and 6135.78 for Jaeger clusters.

So it really isn't the steering column and you will soon find out if it was the pinion. Does it looks like the refurbished pinion had the top seal changed or was it just cleaned and painted black? If in the end it is falty and it's a 10 teeth pinion I might be interested by it even if it's junk.

If it's stock it should be 0 280 160 227, 2.5 bar. Cars before 02/84 had another one but as a spare part you're supposed to order this one plus the corresponding injection ramp.

There is a torsion bar inside the pinion, when locked does it feels springy or solid?

Maybe the guy was afraid to rev it up to 7000 rpm or maybe the car had a problem, like the clutch pedal sensor that can lower the rev limit to 6800 rpm.

Welcome here. The RC is using the closer ratios "T" gearset with a 19x75 final drive and 205/40 ZR17 tyres. The 607 has a better top speed but isn't supposed to have the upper hand under 200 km/h: https://zeperfs.com/en/duel1101-1291.htm The EW10J4S engine was also used on the 307 and Citroën C4 but that's about it. You can find the Peugeot part numbers here: http://catcar.info/peugeot/?lang=en&l=

Welcome here. The 1.6 HDI "DV6" is a PSA-Ford engine but it seems to be (very) loosely based on the PSA TU engine so that some tooling could be reused. I too think the 2.0 HDI has more potential but on the other hand going with the 1.6 HDI means that you can also bolt the 1.6 turbo petrol 150hp EP6DT as they have the same bolt pattern and the engine blocks are generally close. BMW was using a longitudinal mounted EP6 as the N13 engine, I don't know if the bellhousing and engine mounts can be used on a transverse EP6/DV6 but it's worth checking. There is a bellhousing to mate a XUD/XU engine to a BA7/5 gearbox, it's on the JPX Montez a Brazilian 4x4. The 2.0 HDI have the same bolt pattern and the early ones are slanted at the same 30° angle.

Champion G61, also used on the Ferrari F40. Often replaced by NGK C8E.

They looks like it but they aren't, the pressure is quite low compared to a diesel injection pump so they are probably more fragile.

That's not a simple question. It's a Continuous Injection System (CIS) so the pressure is what varies with engine load and also on cold start. https://k-jet.biz/tests/ https://www.volvoclub.org.uk/tech/fuel_injection/BoschMechanicalFuelInjection.pdf http://www.type17.ch/downloads/Injection/Bosch - K-Jet - Workshop Manual.pdf

Because it's so hard you can at least dig straight. As long as you don't find any huge rock and no water consider yourself lucky.

It's a K-Jetronic with lambda. https://cis-jetronic.com/index.php?rt=product/category&path=65_66

Whith this white paint it's not as difficult: no metal flakes, no clear coat and most importantly there is not much color to loose even after years of direct sunlight. You mostly have to choose the right shade and polish the car so that the shine is the same all around. I have seen blue-grey cars with allmost no blue left, it's simply grey until you open the door and see how it was when new. A partial respray on those must be quite the challenge.
